CARTRIDGE FOR REDUCED SHOT.

Specification of Letters Patent.

\ Application filed September 25, 1909. Serial No. 519,572.

T 0 all whom it may concern:

Be 1t known that I, F Eonnrco HARTMANN,

civil engineer, citizen of the Argentine Republic, and residing at 25 de Mayo street, 2-10, Buenos Ayres, Ar entine Republic, have invented a Cartridge or Reduced Shot, of which the following is a specification.

It is the object of the present invention to provide a cartridge for reduced shot adapted to be equally well used in any class of fire arms, such as rifles, revolvers, etc., having any desired caliber.

The essential and principal feature of my invention consists in providing a specially constructed cartridge for reduced shot, adapted to be used in portable military fire arms by simply introducing an auxiliary barrel into the barrel of fire-arms. or by suitably using said barrel itself as holder for said cartridge.

The cartridge forn'ling the object of this invention has the general appearance of an ordinary military fire arm cartridge of the class for which it is intended to be used.

In the accompanying drawings forming part of this specificationFigure 1 represents a rifle cartridge in side elevation. Fig. 2 is a longitudinal section through the same, the cartridge proper being represented in full view. Fig. 3 is a longitudinal section through a preferred form of easing. Fig. -l

is a rear View of the same. Fig. 5 shows in section an outside casing constituting the shell of the usual military cartridge. Fig. 6 is a rear view thereof. Fig. 7 shows in elevation a cartridge of small caliber to be used in a rifle of larger caliber. Fig. 8 shows in section a percussion hammer used in combination with the cartridge for reduced shot. Fig. 9 is a rearview thereof. Fig. 10 is a 'front view of the percussion hammer, Fig.

8. Fig. 11 is a longitudinal section through a casing guiding a cartridge of reduced shot for repetition pistols. Fig. 12 shows the percussion hammer shown in Fig. 8 in elevation, with the exception that in place of the lever spring, acircular rim is provided. Fig. 13 is a rear view of the percussion hammer shown in Fig. 12. Fig. 14: is a side view partly in section of a military rifle showing its chamber stocked with cartridges of reduced shot. Fig. 15 is a detail View on a larger scale demonstrating the way to secure 1 the barrel for reduced shot in the rifie bore. Fig. 16 is. anelevation of a cartrldge used for repetition pistols.

The reduced shot cartridges for military rifles are composed of the following elements:-1. An'exterior shell 6 constituting the shell 'of the customary military" cartridge, from which part of the neck and the bottom have been removed. 2. A casing 0 provided with neck part and bottom flange, which is introduced into the shell b. 3. A cartridge a of small caliber as commonly used in rifles. 4. A percussion hammer d which may be of any type, preferably as shown in F igs'. 8 or 12.

The percussion hammer represented in Fig. 8 consists of a'cylindrical body (I, a head somewhat larger than said body, provided with percussion points 72, causing the fulmination of'the cartridge (4 by colliding with the cap of the same, alever spring 76 provided with the curved end 1" embedded in a. circular groove 0 of the outer mantle 0, so as to be retained in its adjusted position, and finally a cylindrical perforation c, in which a piece of soft metal is introduced; the point of'the percussion ham-mer of the rifle then produces the explosion of the loaded cartridge by contacting with said piece of soft metal. 0

The percussion hammer illustrated 111 Fig. 12 is mainly the same as that shown in Flg. 8, with the exception that instead ofthe lever spring n, a circular rim m is provided.

A cartridge of reduced shot for repetit on pistols consists of a shell q, provided w1th a circular groove Z and an internal groove 70, in which a circular spring J is lodged, tending to keep the percussion hammer 2' hav ng percussion points it in its place, and a c1rcular recess 9 is adapted to receive a piece of soft metal, withwhich the percussion hammer of the gun collides.

When using my cartridge of reduced shot for military rifles, the cartridges are placed in the chamber of the rifle in any desired number, the same as using military eartridges.

The reduction barrel is secured in the inside of the bore of the rifle barrel, by 1ntroducing into the latter barrel, a barrel 1'' of less interior diameter, which occupies half of the room allotted in the military rlfle for the reception of the neck of the shell. This can be clearly seen in Fig. 15. The auxiliary barrel is adjusted by a nut from the muzzle of the rifle.

The principal advantage obtained by uspresent invention, is to be seen in the fact that the same can be used in the exercise of target shooting with military rifles without damage or in ury for the latter, the cartridges may also equally well be used in discalibrated rifles.

Another important feature of the present invention is to be seen in the fact that the cost of the bullet, which is the only object being lost when firing the cartridge a is insignificant, and, that the other parts of the cartridge are not damaged in any way, as by contmual wear and tear, this refers also to the reduction barrel 7 Having thus described my invention, what I claim is 1. A cartridge for reduced shot comprising in combination with an outer shell corresponding to the caliber of the fire arm to be used, a casing having aneck and a bottom flange, a cartridge of. smaller caliber located in said nec'k part, a percussion hammer interposed between the percussion hammer of the fire arm and the percussion cap of the cartridge of smaller caliber, means to retain said percussion hammer in its position of rest, and means adapted to be engaged by the percussion hammer of the fire arm to cause the explosion of the cartridge of smaller caliber.

2. A cartridge for reduced shot comprising in combination with a shell corresponding to the caliber of the fire arm to be used, and having a neck'and a bottom flange, a cartridge of smaller caliber located in said neck part, a spring retained percussion hammer, interposed between the percussion hammer of the fire arm and the percussion cap of the cartridge of smaller caliber, and means adapted to be engaged by the permission hammer of the fire arm to cause the explosion of the cartridge of smaller caliber.

3. A cartridge for reduced shot comprising in combination with, an outer shell corresponding to the caliber of the fire arm to be used. a casing having a neck and a bottom flange, a cartridge of smaller caliber located in said neck part, a spring retained percussion hammer interposed between the percussion hammer of the fire arm and the percussion cap of the cartridge of smaller caliber, a cylindrical recess at the rear end of one of said percussion hammers, a piece of soft metal within said recess adapted to be engaged by the percussion hammer of the fire arm to cause the explosion of the cartridge of smaller caliber.

4. A cartridge for reduced shot comprising in combination with a shell corresponding to the caliber of the fire arm to be used, and having a neck and a bottom flange, a cartridge of smaller caliber located in said neck part, a spring retained percussion hammer interposed between the percussion hammer of the fire arm and the percussion cap of the cartridge of smaller caliber, percussion points at one end of one of said hammers and a circular recess at the other'end for the reception of a piece of soft metal adapted to be engaged by the percussion hammer of the fire arm to cause the explosion of the cartridge of smaller caliber.

5. A cartridge for reduced shot. COHIPPiS".

ing in combination with an outer shell, an auxiliary barrel for reducing the caliber of the fire arm to be used, a casing having a neck and a bottom flange, a cartridge of smaller caliber located in said neck part, a percussion hammer interposed between the percussion hammer of the fire arm and the percussion cap of the cartridge of smaller caliber, means to retain said percussion hammer in its position of rest, and means adapt ed to be engaged by the percussion of the fire arm to cause the explosion of the cartridge of smaller caliber.

In testimony whereof I affix my signature in presence of two witnesses.
